Title: Oscillation preventing device for spud type floating body
Inventor: MIYAGAWA NORIHISA
IPC: B63B21/50
Filed: 1987-05-22
Abstract: PURPOSE:To prevent securely the oscillation of a floating body, by arranging inside a cylinder a piston connected to a spud and the floating body, and by communicating the upper chamber with the lower chamber of this piston. CONSTITUTION:Inside a cylinder 5 connected to a floating body 2, a piston 8 is arranged so as to be freely movable up and down, and the lower end of the rod 10 of the piston 8 is connected to a spud 3 driven into the sea bottom 4. And, the piston upper chamber 6 inside the cylinder 5 and the piston lower chamber 7 therein are communicated via a flow passage 9. Accordingly, as the piston 8 moves up and down inside the cylinder 5, liquid moves between the upper chamber 6 and the lower chamber 7 inside the cylinder 5. Thus, the short-period up-and-down oscillation of the floating body due to the wind and waves can be restrained by the resistance at the time when the liquid passes through the flow passage 9. Furthermore, the slow up-and-down movement of the floating body 2 due to the tide can be smoothly followed up.

Title: Magnetic head and manufacture of the head
Inventor: TOURIYUU KOUJI
IPC: G11B5/127
Filed: 1990-05-17
Abstract: PURPOSE:To reduce heat generation caused by the loss of an eddy current by providing plural slits or spacers in a direction orthogonal to plural magnetic gaps in the head. CONSTITUTION:For explaining the process manufacturing the magnetic head, magnetic gaps G1 and G2 are machined on an integrally formed front core 1 and slits 5 are machined by using thin grindstone. Next, when a current flows to a coil 2 in the case of erasing information recorded to a tape, magnetic flux is generated in the front core 1 and a back core 3, and especially in the front core 1, the eddy current loss is generated to generate the heat in the front core 1. However, since the front core 1 is separated in the direction orthogonal to the magnetic gap, the eddy current loss is decreased and the heat generation is suppressed.
